Application filed July 16,

This invention relates to new and useful improvementsin scafford brackets and has for its primary object, the provision of a novel and simplified bracket of the above, character ,so constructed that all of the joints thereof are tleXible and further, to provide such a bracket that may bereasily and quickly folded when not in use and which, when so folded, will occupy a mini mum amount of space.

Another object of the presentinvention is to provide such an improved bracket of the above character including a pair of hanger bars, a pair of scaffold supporting arms pivot-ally secured to said hanger bars, and ,a'leg for bracing and retaining said supporting arms in a horizontal position together with improved and simplified means for flexibly connecting the adjacent ends of the said hanger bars and bracing leg together. i

A further object of the present 1nvent1on is to provide such an improved bracket of the above character Which is simple yet durable in construction, practical and efficient in use, easy andcheap to manufacture and one which can be placed upon the market at a small cost and readily secured in position for use.

Numerous other objects and advantages of the present invention will becomemore readily apparent during the course of the following description when taken in connection with the accompanying drawings.

In the drawings forming a pal-tot this application and wherein like characters of reference denote corresponding parts throughout the several views:

Figure 1 is a side elevationof an unproved scaffold bracket constructed in accordance with the present invention showing the same secured in position for use.

Figure 2 is a front view thereof.

Figure 3 is a detail perspective view of the forward end of the bracing leg.

Figure 4 is a top plan view of Figure 1.

Figure 5 .is a sectional view taken on line .5-5 of Figure 2.

Figure V6 is a detail sectional view taken on line 66 of Figure 4:.

Referring now more in detail to the accompanying drawings, it will be seen that the present improved scaffold bracket em bodies in its construction a pair of vertically disposed downwardly converging hanger 192s. Serial-N0. 'ie'gao'oi.

bars 10 and ll each of Which issubstans tially L-shaped in cross sectionand includes a flat base portion 12jand the right. angularly and forwardly directed flange-l3.

' The upper end portions 14L and 1501": the said hanger bars are directed at an angle to the lower portions thereofand are arranged in spaced substantially parallel relation rel-ative to one another when the bracket is secured in position for use. The base; port1ons12 of the end portions 1.4 and 15 are preferably provided with key hole slots ldwherebythe bracket may beeasily and quickly secured in positionas Will be readily understood. a v The Rfianges 13 of "thesaid hanger bars 10 andll projectdownwvardly beyondthe base portions IQthei-eof and are bent later- I ally and outwardly to provide the terminal ears 1? and 18 which are substantially par allel with one another when the bracket is secured in position and through which is "re-- supporting ,arms, each of whichisalso-sub stantially L.- hapedin cross section as shown. to advantage in .Figure 6 andfcomprises a top port on 24 provided at .itsouter rlongitndinaledge with a depending flange The depending flanges 255 mm supporth ing arms 22 and 23 extend rearwv ardly be yond the top, portions 24; thereof and area pivotally connected as at 26 to. the forward ly directed flanges 13. of the hanger .Joars. l0 and 11 adjacent the upper ends thereo The forward ends of the supporting arms- 22 and 23 are connected by means of a trans verse bridge plate27 pivotally secured-as 1 at 28 to the top portions 24 supporting arms.

For the purpose of bracingthe scaffold I supporting arms 22 and 23 andfor retaining them 1n ahorizontal posit on, there" is pro-- vided a bracing leg 29 of substantially T- I shape in cross section and comprisinga top of the said l .tudinal edges with the depending web 31.

The web 31 projects beyond the top portion 30 of the bracing leg 29 at the inner end thereof to provide the terminal foot 32 which is positioned between the terminal ears-17 and 18 and also loosely receives the transverse pivot pin 19 therethrough. Passing transversely through the web 31' ad'- jacent the forward end of the bracing leg 29 is a supporting pin 33 upon the opposite ends of which are securedthe sleeves 34.

When it is desired to secure the bracket in position, the key hole slots 16 are first engaged over suitable supporting elements such as nails, screws or the like in the well known manner, afterwhich the supporting arms: 22 and 23 are raised to a horizontal position and the upper end of the bracing 29 is then inserted between the said arms so that the sleeves 3 L carrier by the transverse pin 33 will engage the under or bot tom faces of the top portions 24: of the said supporting arms.

I When it is desired to fold thebraclret, the. bracing leg 29 is first swung upwardly and inwardly sovthat'it will be positioned between the hanger bars and 11 and the bridge plate will act as a stop to limit theinward "swinging movement of said le The supporting arms 22 and 23 are then "swung downwardly and inwardly so that' the flanges thereof will rest upon the base portions l2 of the hanger bars lO'and 11 outwardly of the flanges 13 thereof.

' Due. to thefact that the openings in the terminal ears 1? and 18 through which the pivot pin 19 passes are somewhat larger than.

said pin, there is provided a flexible joint so that the hanger bars 10 and 11 can be forced inwardly into close proximity relative to one another so that the foldedbraclr et will occupy a minimum amount of space and considerable less spacethan if the I hanger bars were not flexibly connected.

Y From the foregoing, it is believed that the construction and application of the present to be understood that changes in the de invention-will be readily apparent and it is tails of construction may be resorted to without departing from or sacrificingthe spirit of the-invention so long as such changes fall within the scope of the appended claims.

cross section adapted to be arranged with the outer face of the flange of each in the same plane to position the outer faces of the other flanges in side opposed'relation,

said bars converging at their lower ends and having the opposed flanges extended at the lower ends beyond the other flanges and further arranged in spaced parallel relation, scaffold supporting arms each pivotal- 1y secured at one end to one of said opposedv flanges adjacent the upper end thereof, said arms converging at their outer ends, a bridge plate pivotally connecting the converging lower ends of said bars inwardly of the ends of said extended flanges, a bridge plate pivotally connecting the con vergent ends of said arms, a brace leg of substantially 'l shaped cross section pivotally connected at one end between the ends of said extended flanges, a pin member projectinglaterally from the web of said brace member upon each side of the same adjacent the other end thereof, and a sleeve surrounding each end of said pin and engaging beneath a supporting arm, the upper end of said brace leg; overlying the bridge plate connecting the arms.

2. A scaffold structure of the. character described, comprising a hanger element, a pair of forwardly extending and converging scaffold supporting arms each pivotally secured at one end to said hanger element, eachvof said arms having an inwardly di-,

rected flange extending throughout the ALEXANDER E. METZ.
